Legionella pneumophila Subspecies fraseri Infection after Allogeneic Hematopoietic Stem Cell Transplant, China.

We describe an immunosuppressed patient with bacteremia and pneumonia caused by Legionella pneumophila subspecies fraseri in China. We confirmed this diagnosis by using nanopore sequencing of positive blood cultures and subsequent recovery from buffered-charcoal yeast extract culture. Nanopore sequencing is an effective tool for early diagnosis of atypical infections.
